Why this works:
If your iPhone battery drains fast, one simple thing you can do is turn off your iPhone every week. Turning your iPhone off gives it a fresh start and can resolve minor software issues (such as an app crash) that was going on in the background of your iPhone.
For this tip, make sure you’re not doing a hard reset, as it won’t resolve the software problems that could be fixed by turning your iPhone off the normal way. In fact, a hard reset may actually corrupt software files on your iPhone, which could make your battery issues even worse!
